Bitcoin cash is itself the definition of what Bitcoin should be like today, the world's electronic money, highly decentralized and secure.
It is one of the hard forks of BTC, born as a disagreement by the community currently using the Bitcoin roadmap published by Satoshi Nakamoto.
What I like most about BCH is that you can basically use and acquire it in any exchange as well as with bank or fiat cards, in addition to being accepted by multiple payment services or goods purchases in the real world. Considering the above, this cryptocurrency has a good performance as an asset for trading in general for this type of services, it has good liquidity.
Currently there are great discussions since the last halving of BCH, since the amount of computing equipment destined to this asset was reduced, an important part of mining has been centralized, which can be counterproductive since if one of the mining groups manages to occupy more 50% can modify transactions on the network. Currently the highest network rate is handled by Bitmain.
The last blow this project had was the hard fork of BCH and BSV making the BCH block heavier, leading to more centralization.
